ABSTRACT

The present invention is drawn to a composition and method for lifting color and/or imparting shine onto keratinous substrates, the composition containing: (a) at least one phospholipid; (b) at least one nonionic surfactant; (c) at least one compound chosen from an alkyl ether carboxylic acid, an alkyl ether carboxylate, a fatty acid having from about 6 to about 40 carbon atoms, and mixtures thereof; and (d) at least one oxidizing agent. The compositions of the present invention may optionally contain at least one thickening agent, at least one alkaline agent, at least one fatty substance other than a fatty acid, and at least one salt.

FIELD OF THE INVENTION

The present invention relates to novel compositions for lightening the color of hair and for imparting shine based on a combination of at least one phospholipid, at least one nonionic surfactant, at least one compound chosen from an alkyl ether carboxylic acid, an alkyl ether carboxylate, a fatty acid having from about 6 to about 40 carbon atoms, and mixtures thereof, and at least one oxidizing agent.

BACKGROUND OF THE INVENTION

It is known that consumers desire to use cosmetic and personal care compositions that enhance the appearance of keratinous substrates such as hair and skin by changing the color of the hair or skin and/or by imparting various properties to hair or skin such as shine and conditioning. The process of changing the color of hair can involve either depositing an artificial color onto the hair which provides a different shade or color to the hair or lifting the color of the hair, such as for example, from a dark brown shade to a medium brown or a light brown shade.

The process of lifting the color of keratinous substrates such as hair, also known as lightening, generally requires the use of compositions that comprise at least one oxidizing agent. The role of this oxidizing agent is to break down the melanin of hair, which, depending on the nature of the oxidizing agent present, results in a more or less pronounced lightening of the color of hair fibers. In certain instances, hair lightening compositions may possess an alkalinity such that these compositions may have a pH value of above 7 and may require the presence of an alkaline agent.

In order to improve the performance of compositions for lifting color, the use of new and additional ingredients and novel combinations of ingredients are continuously sought; however, the choice of ingredients could pose difficulties insofar as they must improve the lifting capability of the composition without being detrimental to other properties of the composition such as its application, rheology or viscosity properties and/or resulting into more disadvantages such as increased damage or a less healthy look to the hair. It is therefore, important to provide the consumer with a hair lightening or lifting composition and method that can lift the color of the hair in an efficient manner, not only to the degree of lift desired, but also with the added benefit of obtaining better lift compared to current products and methods without resulting in more damage to the hair. At the same time, it is also desirable that such a composition and method can provide other advantageous properties to the hair such as shine, conditioning, and a healthy appearance to the hair. Furthermore, it is preferable to formulate such compositions that are less costly to manufacture by requiring less ingredients and/or lower levels of ingredients.

Thus, the objective of the present invention is to obtain novel compositions for lifting or lightening the color of the hair. Another objective of the invention is to obtain compositions that impart desirable shine to the hair and other advantages to the hair such as conditioning, a healthy appearance and less damage to the hair. Finally, it is an objective of the present invention to provide a composition that effectively lifts color with lowered cost of production.

EXAMPLES

The following example is intended for illustrative purposes only, and is not meant to unduly limit the scope of the invention in any way.

Example 1 Color Lift Study

Ten (10) g of each of the compositions below were mixed in a 1:1 ratio with a 20 volume hydrogen peroxide developer. The pH of each final mixture was about 10. Each final mixture was then applied onto a designated swatch of natural brown level 3 hair 0.5 cm width, 15 cm length), commercially available from IHIP, International Hair Importers.

Formula Ingredient A Formula B Formula C Formula D Formula E Lecithin 1.0% 1.0% 1.0% 1.0% 1.0% PPG-5  15%  15%  15%  15%  15% Ceteth-20 Laureth-11 1.0% 1.0% 1.0% 1.0% 1.0% Carboxylic Acid Mineral oil 1.0% 1.0% 1.0% 1.0% 1.0% Ethanolamine 3.0% 3.0% 3.0% 3.0% 4.0% Sodium Sulfate 4.0% 3.0% 2.0% — — Water Q.S. Q.S. Q.S. Q.S. Q.S.

Two control formulas comprising the base formula of a commercial product, L'Oréal Preference™ were also applied onto separate hair swatches. Control formula 1 contained 4% ethanolamine as the alkaline agent and control formula 2 contained 10.2% ammonium hydroxide as the alkaline agent.

All swatches were processed for 30 minutes at a 27° C. heating plate, rinsed for 1 minute (80 gph, 32° C.), and dried. Color measurements were taken before and after treatment as L values which correspond to the degree of lightness of the color of the hair, using Konica Minolta Spectrophotometer.

The final ΔL (change in L) value measurements on the swatches treated with Formulas A to E were 10.4, 8.62, 7.23, 5.06, and 4.43, respectively. The final ΔL (change in L) value measurements on the swatches treated with control formulas 1 and 2 were 4.21 and 9.63, respectively. A greater ΔL value indicates a greater change in the lightness of the color of the hair which indicates a greater lift in color. The results show that formulas A to E lightened the color of the hair significantly better than or comparably to the control formula 1, while formulas A, B and C which contained sodium sulfate lightened the color of the hair significantly better than formulas D and E which did not contain sodium sulfate. Moreover, formulas A to C required a lower amount of the alkaline agent, monoethanolamine, compared to that used in formula E and control formula 1 in order to achieve significantly greater lightening effects; this is more advantageous since lower levels of the alkaline agent are more desirable. As for control formula 2, this formula contained a higher level of alkaline agent, that is, 10.2% of ammonium hydroxide, which is less desirable.

It will be apparent to those skilled in the art that numerous modifications and variations can be made without departing from the spirit or scope of the invention.
